// 数据
var data = [{

"type": "小白"

}]

// 分组
function groups(data){
let map = {}
let result = []

// dataIndex.type == 数据的type字段
for (let i in data) {
let dataIndex = data[i]
if (!map[dataIndex.type]) {
map[dataIndex.type] = [dataIndex]
} else {
map[dataIndex.type].push(dataIndex)
}
}

Object.keys(map).forEach(key => {
result.push({
group: key,
data: map[key],
})
})
return result
}
console.log(groups(data));
